Tsume shogi (詰将棋 or 詰め将棋, tsume shōgi) or tsume (詰め) is the Japanese term for a shogi miniature problem in which the goal is to checkmate the opponent's king. Tsume problems usually present a situation that might occur in a shogi game (although unrealistic artistic tsume shogi exists), and the solver must find out how to achieve checkmate. It is similar to a mate-in-n chess problem. The term tsumi (詰み) means the state of checkmate itself. The verb form is tsumu (詰む) "to checkmate". (The related term tsumero 詰めろ refers to the slightly different concept of "threatmate". See: Hisshi.)
